Circles are round plane figures whose boundaries consist of points equidistant from a fixed point. Sector of a circle Sectors are sections of a circle that are created by two radii and an arc. Major sector –a major sector has a central angle which is more than 180°.180°. Minor sector...

Parallel lines can be recognised by their equations by checking if their gradients are the same. This may require some rearranging. E.g. Show that y=−2x+4y=−2x+4y=−2x+4 and 4x+2y=94x+2y=94x+2y=9 are parallel. The gradient of the first line is −2−2−2. We need...
